Abstract (en)
[origin: WO2012074121A1] The present invention provides a highly stable HFO refrigerant composition for use in a vapor compression-type refrigeration system, having improved slidability for the sliding portions of the vapor compression-type refrigeration system. More specifically, the present invention provides an HFO refrigerant composition comprising at least one type of HFO refrigerant and a polymer of halogenated propene represented by C3HaFbClc (provided that a + b + c = 6, a = an integer of 1 to 3, b = an integer of 3 to 5, and c = an integer of 0 to 1) that is an oligomer having a molecular weight of 200 to 900.
